DOOR CHECK AND SPRING.

. SPECIFICATION forming part of Letters Patent No. 703,371, dated July 1, 1902.

Application filed September 16, 1901. Serial No. 75,433. (No model.)

To rtZZ whom it rnaty concern:

Be it known that I, VICTOR BEAUREGARD, a citizen of the United States, residing at Boston, in the county of Sufiolk and State of Massachusetts, have invented new and useful Improvements in Door Checks and Springs, of which the following is a specification.

This invention relates to that class or type of pneumatic door checks and springs wherein a cylinder is pivotally connected at one end and contains a piston havinga piston-rod connecting through intermediate devices with the door and by an intermeshing gear with a spring contained within a barrel or casing.

The invention is an improvement upon the door check and spring for which I obtained Letters Patent of the United States dated June 5, 1900, No. 651,098.

The object of this invention is to improve, simplify, and render more economical and practical the character of door checks and and spring such as, for instance, the sagging of the door or inaccuracy in the manner in which the check is'applied to the door and easing.

The object of the invention is still further to provide means whereby different-size springs may be used in the same spring-casing.

The invention consists in a door check bracket adapted to be attached to a door-casing or door and an angle-piece detachably connected to said bracket.

The invention further consists in a bracket adapted to be attached to a door-casing or door and an angle-piece reversibly and de tachably connected to said bracket, said angle-piece formed to receive the spring-casing of a door-check.

The invention further consists in a doorcheck having a spring-casing,a bracket adapted to be attached to a door-casing or door, and an angle-piece detachably connected to said casing and to said bracket.

The invention again consists in a link for a door-check provided with a right-angle projection at one end thereof, a bracket adapted to be fastened to a door or door-casing, and a swivel-block connecting said link and bracket rotatably mounted upon said right-angle projection and rotatably mounted upon said bracket.

Theinvention again consists in a door check and spring having a spring-casing consisting of a stationary member and a rotary member in combination with a spring, one end connected to said rotary member and the other to said stationary member, and a link interposed between the outer end of said spring and said stationary member.

Referring to the drawings, Figure 1 is a plan view of my improved door check and spring, showing the same attached to a right-hand door upon'the hinge side thereof, the casing and door being shown broken away and partly in section. Fig. 2 is a detail vertical section taken on the line2 2 of Fig. .1 looking toward the right in said figure. Fig. 3 is a side elevation of the spring-casing and bracket of the .the hinges thereof, a portion of the casing and door being shown in section and a portion of the holder broken off. Figs. 4: and 5 are plan and side views, respectively, of myimproved link and bracket. Fig. 6 is a section taken on the line 6 6 of Fig. 4. Fig. 7 is a perspective view of my improved bracket and anglepiece, showing the parts inthe respective positions in which they are placed when applied to the casing of a door. Fig. 8 is a perspective view of my improved bracket and anglepiece, showing the parts in the respective positions in which they are placed when applied to the door. Fig. 9 is a'detail side elevation of the angle-piece, Fig. 10 is a section taken on line 10 10 of Fig. 7. Fig. .ll'is a plan View showing my improved link attached to another form of doorcheck, the door and casing being shown partly broken away and in section. Fig. 12 is a section taken on line 12 12 of Fig. 3. Fig. 13 is a perspective View of the link-plate which connects the outer end of the door-spring to the spring-casing.

- My improved door check and spring is substantially the same as the door check and spring shown and described in the patent hereinbefore referred to as far as the operation and construction of the check. is concerned and the means by which the piston in said check is operated, and it is not, therefore, necessary to enter into a detailed description of the operation of said parts.

In the drawings, 15 is a pneumatic cylinder, having a cap 16 soldered or brazed thereon. Said cylinder is screw-threaded at 17 and is screwed into a hole tapped in the cylindrical boss 18, formed upon the holder 19. Said holder 19 has a cylindrical projection 20 formed upon its under side and constructed with a bore or hole 21, whereby the projection is adapted to fit and turn freely upon the Vertical hollow bearing 22 of the cylindrical spring-casing 23. Said bearing 22 is cylindrical upon its outside and has a square hole 24 extending vertically and longitudinally through said bearing to receive the arm 26 of the angle-piece 25, as hereinafter described, said angle-piece being square in cross-secnon.

In order that the check may be applied to the hinge side of a right or left hand door or to the side opposite from the hinges by the use of a single bracket, I construct abracket 28, as shown in Figs. 7 and S, with the anglepiece 25 detachably attached thereto by means of a set-screw 29. The bracket 28 consists of a plate 30, having a boss 31 formed integral therewith and at right angles to the face of said plate, and having another boss 32 formed integral wit h said plate 30 and extending parallel to the face thereof. The boss 31 has a square hole formed therein extending lengthwise thereof throughout its entire length. The boss 32 has a V-shaped slot or recess 33 therein opening from the back face of the plate 30 upon the bracket 28 to receive the arm 27 of the angle-piece 25. The hole extending through the boss 31 extends from said recess 33 to the opposite face of the bracket 28 or, as hereinbefore set forth, through the boss 31.

'When the plate 30 is attached by screws to the hinge side of a door, as shown in Figs. 1 and 2, the arm 27 of the angle-piece 25 is inserted in the boss 31, as in Fig. 8. A collar 34 is then placed upon the arm 26 ofsaid angle-piece and the spring-casing 23 slipped upon the arm 26, the lower side resting 011 the collar 34 and is held upon said arm by a washer 35 and split pin 36.

When the check is applied to the side of the door opposite the hinges, the arm 27 of the angle-piece 25 is removed from the boss 31, Fig. 8,the angle-piece as a whole reversed, and the arm 26 passed downwardly through the boss 31, thus bringing the arm 27into the slot 33 in the boss 32, as shown in Fig. 7. The spring-casing 23 and the parts attached thereto are held on said angle-piece 25 by means of the washer 35fand split pin 36.

In Fig. 1 the bracket 28 is shown attached to the door 37 upon the hinge side thereof, and the cylinder-cap 16 is connected by a link 39 through a pivotal block 40 to a bracket 41, fast to the casing 38. The link 39 is made in two parts 42 and 43. The part 42 is pivoted at 44 to the cap 16 and is adjustably connected by screw-threaded engagement with the rod 43, forming the other part of said link 39. The rod 43 at the end opposite its screwthreaded portion is bent at right angles at 45 and passes through a horizontal hole 46 in the pivotal block 40. Said pivotal block is pivoted upon a vertical pin 47, which passes through ears 48 48 upon the bracket 41, said bracket being adapted to be attached by screws to a door or to a door-casing.

It will be seen that if a door sags or if the outer end of the link 39 is raised or lowered the horizontal right-angle bend 45 will turn freely in the horizontal hole 46 inthe pivotal block 40, so that no cramping will ensue, and as the door is being opened or closed and. the link 39 assumes different positions in the horizontal plane it is evident that said pivotal block 40 will turn at different angles in a horizontal plane upon the vertical pivotal pin 47, and, again, it will be seen that any relative position assumed by the door, door-casing, or the check attached thereto which would tend to cause the moving parts of the check and its connecting-link to bind one upon the other and cause friction would still further be accommodated by the two parts 42 and 43 of the link 39 turning upon each other where they are in screw-threaded engagement, so that by the construction hereinbefore set forth the link 39, together with the pivotal block 40, contains all the advantages of a ball-joint, together with the feature of being able to adjust the length of the link without any of the disadvantages of a balljoint and of the large expense attending the manufacture of such a joint.

It is often desirable to change the relative size of a spring to the checking medium or cylinder to accommodate the check to varying conditions of wind-pressure, and in order to enable me to use different-size springs with the same spring-casing I provide a plate 49, Fig. 12, one end of which engages a slot 50 in the interior of the spring-casing 23 and the other end of which engages the outer end 51 of the helical spring 52, the inner end 53 of said helical spring engaging vertical slots 54, formed in the periphery of the projection 20 upon the holder 19.

In Figs. 1 and 2 the check is shown as applied -upon the hinge side of a right-hand door. If it is desired to apply the check to the hinge side of a left-hand door, the washer 35 and split pin 36 are removed and the ICC check, together with the spring-casing, removed from the arm 26, turned upside down, and replaced upon the arm 26, the washer 35 and split pin 36 again being placed upon the arm 26, the brackets 28 and 41 being placed in the same relative location to the righthand hinge that they are shown as occupying to the left-hand hinge in said Fig. 1. When the checkis applied to the side of the door opposite the hinges,it is placed upon thebracket, as hereinbefore described, and shown in Fig. 3, the bracket 28 being attached to the casing 38 and the bracket 41 being attached to the door.

In Fig. 11 I have illustrated my improved link attached to an arm of a door-check 56 of different construction, said arm 55 being fastened to a rotary spindle 57 for the purpose of illustrating the fact that my improved link and pivotal block, together with the bracket 41, to which said block is pivoted, may be used for difierent styles of doorcheck without departing from the spirit of my invention.

By means of the set-screw 29 the an gle-piece 25 may be adjusted in the boss 31, so as to bring the arm 26, Fig. 8, nearer to or farther away from the plate 30 of the bracket 28, so that the spring-casing, Fig. 2, may be adjusted toward or away from the door. This adjustment is found very convenient in setting up checks, as the face of the door and of the casing vary in their relative location, sometimes being fiush, at other times the face of the casing projecting beyond the face of the door, and this adjustment of the anglepiece, together with the spring-casing thereon, adapts the check to be placed upon casings and doors having varying relations to each other. Again, it will be seen that by loosening the set-screw 29 the angle-piece, together with the check, may be removed from the door without taking the bracket off of said door, this being often desirable when the season of the year does not necessitate a door-check.

Having thus described my invention, what I claim, and desire by Letters Patent to secure, is-

1. In a door-check a bracket adapted to be attached to a door-casing or door and an angle piece detachably connected to said bracket.

2. In a door-check, a bracket adapted to be attached to a door-casing or door, said bracket provided with a recess opening from one face thereof, and a hole extending from said recess to the opposite face of said bracket for the purpose specified.

3. In a door-check, a bracket adapted to be attached to a door-casing or door, in combination with an angle-piece said bracket provided with a recess opening from oneface thereof, and a hole extending from said recess to the opposite face of saidbracket, whereby said an gle-piece may be reversibly connected to said bracket for the purpose specified.

4:. In a door-check a bracket adapted to be attached to "a door-casing or door and an angle piece adjustably connected to said bracket.

5. Inadoor-checkaspring-casing,abracket adapted to be attached to a door-casing or a door and an angle-piece detachably connected to said spring-casing and bracket.

6. In a door-check,a spring-casing,abracket adapted to be attached to a door-casing or door,and an angle-piece adj ustably connected to said bracket and detachably connected to said spring-casing.

7. In a door-check, a bracketadapted to be fastened to a door or door-casing, a link provided with a right-angle projection at one end thereof, and a swivel-block connecting said link and bracket rotatably mounted upon said right-angle projection and rotatably mounted upon said bracket.

8. In a door-check a spring-casing consisting of a stationary member and a rotary member, in combination with a spring, one end of said spring connected to said rotary member, the other to said stationary member, and a link interposed between the outer end of said spring and said stationary member.

In testimony whereof I have hereunto set my hand in presence of two subscribing wit. nesses. t
